Towing my toyhauler home from the desert the other night and the tuner turned down to zero, pedal programmer off and I started to feel a shudder at about 35mph. Came to a slow speed, and check engine light popped on with gear ratio codes for 1-4, hydraulic pressure sensor range code.
About 10 miles later lost all forward gears, but still had reverse.
Came to a stop on the shoulder. Had to call for a tow to my shop, and trailer to get towed home... fml moment.
16k miles on my trans and the first time towing with the tuner turned down and the trans shits the bed.
